Description

Technical Field

[0001] This utility model relates to the field of product inspection tool technology, specifically to an inspection tool for detecting whether the surface pattern of a product is offset. Background Technology

[0002] In modern industrial production, the aesthetics and consistency of product appearance are important indicators for measuring product quality. Among them, the positional accuracy of patterns on the product surface (such as silk screen markings, logos, decorative lines, etc.) directly affects the product's visual effect and brand image.

[0003] Existing inspection methods typically involve manual visual inspection and comparative testing using fixed fixtures. However, in actual inspection, manual visual inspection suffers from low efficiency and strong subjectivity, making it difficult to guarantee consistency. Fixed fixtures require redesigning a new set when products are iterated or patterns are updated, which is costly. Furthermore, when positioning products with irregular outer contours, fixed fixtures may cause placement deviations due to the irregular structure of the product's outer contour, leading to misjudgments and inspection errors. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is to provide a fixture for detecting whether the surface pattern of a product is offset. By setting the replacement components, the fixture can replace the top plate of the corresponding pattern groove according to the position and size of the product pattern. By setting the positioning components, it can adapt to products with irregular shapes, so that the center of the product is aligned with the center of the fixture, reducing false detections caused by placement deviation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a gauge for detecting whether a product surface pattern is offset, comprising:

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] This application provides a fixture for detecting whether the surface pattern of a product is offset, which solves the problem of high cost caused by the need to replace the entire fixture when changing the pattern of an existing product or iterating the product, as well as the problem of false detection caused by placement deviation during the detection process.

[0026] By changing the components, the fixture can replace the top plate of the corresponding pattern slot 202 according to the position and size of the product pattern, without having to replace the entire fixture body 1. Secondly, by setting the positioning components, it can adapt to products with irregular shapes, so that the center of the product is aligned with the center of the fixture body 1, reducing false inspections caused by placement deviations.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] Reference Figure 1 , Figure 2 and Figure 6As shown, a fixture for detecting whether a product surface pattern is offset includes: a fixture body 1, with a product groove 101 at the bottom and a top plate 2 at the top, with a pattern groove 202 at the top of the top plate 2; a replacement component, located between the fixture body 1 and the top plate 2, comprising: a moving groove 3, a locking block 301, and a locking slot 305, with multiple symmetrically arranged moving grooves 3 at the top of the fixture body 1, a locking block 301 inside the moving grooves 3, and multiple locking slots 305 at the bottom of the top plate 2; and a positioning component, located inside the fixture body 1, comprising: a movable groove 102, a movable spring 103, and a limiting block 104, with multiple movable grooves 102 on the inner wall of the product groove 101, a movable spring 103 connected inside the multiple movable grooves 102, and a limiting block 104 connected to one end of the movable spring 103.

[0029] The inspection fixture body 1 is made of acrylic sheet material;

[0030] When performing position detection on the pattern position on the product surface, the inspection fixture body 1 can be placed on the product so that the product is located in the product groove 101. At this time, if the pattern on the product is in the pattern groove 202, it is a qualified product. If the pattern on the product cannot be completely located in the pattern groove 202, it is a defective product.

[0031] Since the position and size of patterns on different products may change during the production process due to market demand or design updates, the top plate 2 can be replaced by changing the components. This allows the pattern groove 202 on the top plate 2 to correspond to the position and size of the pattern on the product, facilitating the detection of the pattern position. The entire fixture body 1 needs to be replaced, improving its adaptability to different products or product iterations. During the detection process, the positioning components can adapt to the irregular outer surface of the product, ensuring that the center of the fixture body 1 corresponds to the center of the product. This serves two purposes: firstly, it provides positioning, avoiding misjudgments caused by product placement offset and eliminating human error; secondly, it is compatible with irregular shapes. Combined with the replacement of the top plate 2, the fixture body 1 can perform pattern position detection on products with different shapes, improving its versatility and adaptability.

[0032] Reference Figure 2 , Figure 5 and Figure 7 As shown, multiple movable slots 102 are evenly arranged and distributed. The cross-sectional size of the limiting block 104 is adapted to the cross-sectional contour of the movable slot 102. One end of the limiting block 104 extends into the product slot 101 and is provided with an inclined surface.

[0033] When the fixture body 1 is placed on the product, the product contacts the inclined surface of the limiting block 104, and the inclined surface is squeezed into the movable groove 102, causing the movable spring 103 to be compressed and generate elastic force, which then reacts to the limiting block 104. The multiple limiting blocks 104 are symmetrically arranged, so that the two limiting blocks 104 at corresponding positions clamp and limit the product. By setting multiple limiting blocks 104, the limiting blocks 104 can adapt to the irregular shape of the product, improve the clamping and fixing effect of the product, and limit the center of the product to the center of the fixture body 1, thus achieving the positioning effect of the product.

[0034] Reference Figure 3 , Figure 4 and Figure 7 As shown, the top of the inspection fixture body 1 has a slot 105, and the bottom of the top plate 2 is connected to a fixing block 201 that is adapted to the slot 105. The bottom of the fixing block 201 is flush with the top surface of the product slot 101. The pattern slot 202 passes through the fixing block 201. Multiple moving slots 3 and card slots 305 are evenly distributed, and the moving slots 3 and card slots 305 are positioned correspondingly. The moving slots 3 have an L-shaped cross-section, and the card blocks 301 have a U-shaped structure. One end of the multiple card blocks 301 protrudes from the outer surface of the inspection fixture body 1 and is connected to the same connecting plate. The other end of the card blocks 301 extends into the card slot 305.

[0035] When replacing the top plate 2, press the connecting plates on both sides of the fixture body 1, causing the connecting plates to move the locking block 301 backward, so that the locking block 301 disengages from the corner of the slot 305. At this time, the limiting spring 304 is compressed and accumulates elastic force, releasing the restriction on the top plate 2, so that the top plate 2 can be removed from the fixture body 1. Then, place the new top plate 2 on the fixture body 1 and insert the fixing block 201 into the slot 105, so that the moving slot 3 corresponds to the slot 305. Then, the connecting plate can be released, so that the locking block 301 rebounds under the action of the limiting spring 304, so that the locking block 301 is re-locked into the corner of the slot 305, completing the installation and fixing of the top plate 2.

[0036] Furthermore, a limiting hole 302 is provided on the card block 301, and a limiting rod 303 that cooperates with the limiting hole 302 is connected inside the moving groove 3. A limiting spring 304 is sleeved on the outside of the limiting rod 303.

[0037] During the movement of the locking block 301, the direction of movement of the locking block 301 can be limited by the setting of the limiting hole 302 and the limiting rod 303.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
